Hall sensor signals appear to have noise and error at certain speeds, will they be solve by the team organizers?
The motor in the dynamometer and in the bicycle will be the stock motor, with the stock hall-sensor. It will be the responsibility of the teams to manage the real-life noisiness and inaccuracy of the …April 17, 2019
We expect this to be ready by April 25th 2019.April 17, 2019
User interface for dynamometer testing and the track-testing will be available at the competition. There will be one interface set-up for the dynamometer testing for the competition, and a second set-up for testing and staging, …April 17, 2019
It was specified that the input current is limited to 12A RMS (0.1s average). It was also specified that the output current corresponding to 4V throttle signal should be 15A RMS. At high enough speeds …April 17, 2019
Congratulations, In behalf of the IEEE-IFEC 2019 organizing committee and the IEEE-IFEC steering committee, I am pleased to announce that your team is among the 10 finalists that have qualified to participate in the IFEC-2019 hardware …April 8, 2019
IFEC2019-Technical Reference_Apr1_ April 1st Change Log: Removed 5V current spec for Hall sensors Removed 5V current spec for throttle control & display Updated Throttle Command table to scale from 0 to 15Arms Reverted motor external …April 1, 2019
THIS DOCUMENT HAS BEEN WITHDRAWN. IFEC2019 Teams, The technical reference document has been updated, see the change log below. https://ifec2019.wisc.edu/documents/technical-reference-march-27th/ We are working on the progress report grading. Results will be released soon. Thank you …March 27, 2019

In the latest technical reference under point 22.h.iii you describe the drive cycle. There has been a question about this point before, but was not fully answered to our understanding. The drive cycle is created …February 26, 2019
At present, we expect that the 2500 rpm limit to be enabled during the field test.February 13, 2019
In order for the device to provide continuous output power of 500W the motor would need to run at around 3750rpm. (Power of the electronic load = Xrpm/3000rpm *40V*10A). What is the purpose of the …February 13, 2019
Are there specific simulation and experimental results that should be provided in the progress report or we should enclose the most striking ones based on our own choice?
Will there be a more detailed description of the required contents of the progress report as there was for the Design proposal or will there not be anymore updates on the document which contains guidelines …February 13, 2019
It would be reasonable to assume that the hot spot and case temperature test would be performed with the device running at maximum continuous output power of 500W, but it has been stated that the …February 13, 2019
What is meant by “enter fault mode” at free acceleration test (most recent Technical Reference Document 22f)?
It has not been specified what’s supposed to happen in the fault mode. Should we turn the device off when the speed reaches 2500rpm or just prevent the device from working at speeds above 2500rpm? …February 13, 2019
When the fault conditions are reached, the system will have to provide an indication should be made as required in the technical reference document item 14.E. How the system responds to the fault event to …February 13, 2019
With a selected output power as specified under 22.b.iii and the specified speed limit of 2500rpm there is a maximum output power (of the electronic load) which can be calculated as 2500rpm/3000rpm*40V*Iout. The throttle signal …February 13, 2019

In the provided IFEC Workshop agenda it is stated that the workshop takes place on the 17th of March. In the post about announcement of the second round competition teams it is stated that the …February 13, 2019
Hello, IFEC 2019. I would like to do an early registration to attend the IFEC workshop at APEC 2019. However, I have difficulty in selecting the registration type. I would like to get information about …February 1, 2019
The Technical Sheet specifies a Target Box Volume of 1500 cm^3. We were wondering if this was an upper bound or if the box needs to be relatively close to this volume. We also noticed …February 1, 2019
